Continuous train-to-ground connectivity for CBTC
Maintain reliable communication between trains and trackside infrastructure as vehicles move through the network.
CBTC / CCTV train-to-ground communication
Westermo's train-to-ground solution supports CBTC and multimedia applications with high-availability redundant transmission and continuous links at vehicle speeds up to 200 km/h.
- Scalable L2/L3 support
- Support for narrowband and Urban Rail ITS
- Mission-critical performance and cybersecurity
Continuous connectivity on the move
Signal- and distance-based handover helps maintain communication between the train and operating centre as vehicles move between access points, while redundant links provide fast failover and backup link recovery.
- <500 ms maximum timeout for backup link/failover
- <0.5% typical packet loss in suitable installations
- Active-active and active-passive redundancy supported simultaneously
Prioritise critical traffic
A single train-to-ground radio link can carry control, video, passenger WLAN and other data while keeping applications separated through networks and VLANs. QoS prioritisation ensures critical automation data takes priority over less time-sensitive traffic.
Manage interference along the track
Different sections of a railway can face different sources of radio interference. Multi-frequency operation allows frequencies to be planned along the track, while neighbouring access points can operate simultaneously without interfering with each other.
Train to ground connectivity
Maintain continuous train-to-ground communication with fast handover and redundant connectivity.
Trackside backbone system
Redundant and cost-effective solutions for reaching remote assets along railroad tracks.
